Evidence used

  • No CISA KEV confirmation is currently recorded.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 0.49% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Unknown Unknown and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 3 daysRemediation target: Within 90 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

  • perl-DBI.src as a component of Red Hat Enterprise Linux 6
  • perl-DBI.src as a component of Red Hat Enterprise Linux 7
Summary
A flaw was found in DBI for Perl. An unvalidated numeric placeholder in the `preparse` function can lead to a heap out-of-bounds write. When processing an untrusted statement, a specially crafted numeric placeholder can cause the binder counter to become negative. This results in subsequent placeholders expanding beyond their allocated buffer, leading to memory corruption. An attacker could exploit this to potentially achieve arbitrary code execution or cause a denial of service.

01

What, why and how

DBI versions before 1.652 for Perl allow a heap out-of-bounds write via an unvalidated numeric placeholder that sets the binder counter in preparse. preparse reserves seven output bytes per input byte, the width of the longest ':p99999' expansion. The ':N' branch parses the number with `atoi(src)` and assigns it to the binder counter with no range check, so a statement containing ':2147483648' leaves the counter negative (-2147483648 with glibc, where atoi wraps). Each following '?' then expands through `sprintf(start, ":p%d", idx++)` to ':p-2147483648', 14 bytes with the terminating NUL where the buffer budgets 7. The placeholder limit added in 1.650 tests the counter against 99,999, which a negative counter passes. Any caller that preparses an untrusted statement into ':pN' style placeholders gets a heap out-of-bounds write that grows with the number of '?' marks following the poisoned placeholder. The '?' and '%s' return styles compare the parsed number against the expected sequence and error out, and are unaffected.

Why

The product receives input that is expected to specify a quantity (such as size or length), but it does not validate or incorrectly validates that the quantity has the required properties.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → Improper Validation of Specified Quantity in Input → cause the confidentiality, integrity or availability impact described by the vendor
Attack surface
Network
Privileges required
None: unauthenticated exploitation is possible
User interaction

Attack complexity
Low: no specialised conditions are recorded
Security boundary
Unchanged: impact remains within the vulnerable component's security authority
Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-1284 ↗

CWE-1284: Improper Validation of Specified Quantity in Input. The product receives input that is expected to specify a quantity (such as size or length), but it does not validate or incorrectly validates that the quantity has the required properties.

BSI · German · WID-SEC-2026-3403Oracle Communications: Mehrere Schwachstellen

Ein entfernter, anonymer oder authentisierter Angreifer kann mehrere Schwachstellen in Oracle Communications ausnutzen, um die Vertraulichkeit, Integrität und Verfügbarkeit zu gefährden.

Official advisory ↗
NCSC-NL · Dutch · NCSC-2026-0375Kwetsbaarheden verholpen in Oracle Communications

De kwetsbaarheden betreffen verschillende beveiligingsproblemen in Oracle Communications-producten, waaronder mogelijkheden voor niet-geauthenticeerde en laaggeprivilegieerde kwaadwillenden om via netwerktoegang ongeautoriseerde acties uit te voeren. De kwetsbaarheden hebben CVSS-scores variërend van laag tot kritiek. Van de in totaal 31 kwetsbaarheden zijn vier als kritiek aangemerkt en kunnen 23 kwetsbaarheden zonder authenticatie op afstand worden misbruikt. Succesvol misbruik kan onder meer leiden tot het verkrijgen van ongeautoriseerde toegang tot gevoelige informatie, het wijzigen van gegevens en het verstoren van de beschikbaarheid van getroffen systemen. Sommige kwetsbaarheden vereisen gebruikersinteractie of voorafgaande toegangsrechten, terwijl andere volledig op afstand en zonder authenticatie kunnen worden misbruikt. De vier kwetsbaarheden die als kritiek zijn aangemerkt, CVE-2026-44024, CVE-2026-17544, CVE-2026-71290 en CVE-2026-73194, hebben een CVSS-score van 9,1 of hoger en bevinden zich in verschillende Core-componenten van Oracle Communications Unified Assurance, waaronder Fluentd, PHP, Apache HttpClient en DBI. Deze kwetsbaarheden kunnen zonder authenticatie op afstand worden misbruikt en kunnen een hoge impact hebben op de vertrouwelijkheid en, afhankelijk van de kwetsbaarheid, de integriteit en beschikbaarheid van getroffen systemen. Het NCSC adviseert om de beveiligingsupdates voor de kritieke kwetsbaarheden met voorrang toe te passen.
